The RS PC1, PC2, and PC3, seemed to be made by whoever made the SHARP pocket
computers; with their characteristic 4-position slide switches
(off/on/run/prog).  The RS PC4 is made by whoever makes the series of pocket
computers sold by Casio; with their characteristic "Mode" button. (I say
"whoever" because I suspect that both CASIO and SHARP subcontract to
ceramics companies like RS.) 

I have a Casio FX720P, with a 4K "ram card",  which I purchased in the
electronics district of Tokyo for $50.  It uses the same printer and
cassette interface as the RS PC4 and new PC5 (Which can apparently be
programmed in machine code!)

I have a catalog of these Casio pocket computers which include:

PB110    544bytes  + 1k ram cartridge
PB410    2k or 4k ramcard
FX720    same as PB410 with meta-key for basic functions
(These all share the PC4 interface)


FX750P   two ramcards for up to 8K
PB500    same, but japanese character set

PB300    2k memory, builtin printer

PB700    4k memory 4 line graphic LCD


There may be more by now!

You can get in touch with CASIO in Fairfield, NJ for more info.

I hope that your pocket computer project doesnt involve any fast
typing...
